The long-finned pilot whales can mimic （模 仿）artificial noise, but nobody had previously recorded them. A new study, how

19、ever, found overlap in the cetacean sound book.Pilot whales and orcas（虎鲸），the two largest species of cetaceans, are often seen in the same environments and are similar sizes, and both live in social groups with strong union, says Charlotte Cure, a researcher at CEREMA Lab in France, who was involved

20、 in the study. Orcas compete for food with long-finned pilot whales and are potentially their predators.Evidence from orca stomachs shows they do occasionally eat pilot whales. But pilot whales can mob（成群困住）and chase them away, the only cetaceans seen defending themselves from the strong enemies in

21、this way.Mimicry could serve as additional defense; One assumption is that if they use similar sounds, they may not be recognized as prey, “ Cure says. Pilot whales eating orcas food remains might go unnoticed if they use orca-like calls. This is all underwater, “ she adds, “so these animals rely on

22、 sound fbr detecting their prey and predators. Long-finned pilot whales have shown an ability to distinguish between orca calls with different meanings; Cure suggests that instead of tricking orcas, the callers could instead be presenting a new orca sound to other group members.Additional work would

23、 confirm whether mimicry is actually occurring. Researchers could pair their listening data with direct observations of the animals, interactions in the wild or perhaps even play orca sounds and watch the whales reactions.But if a future experiment used predatory sounds, it would need to be done ver
